Hey again,

so i created an outline on a page (easy) and it got an outline ID, i then create a named destination for that id (returns 1), try to grab the Destination ID from that name (returns 0) and then use it to add a Link which of course doesn't work.

                        linkId = this.getOutlineId(foundMarker[1]);
                        if (linkId > 0)
                        {
                            Console.WriteLine("OutlineId: " + outlineId);
                            if (qp.SetOutlineNamedDestination(linkId, foundMarker[1]) == 1)
                            {
                                Console.WriteLine("Created NamedDestination " + foundMarker[1]);
                            }
                            int destinationId = qp.GetNamedDestination(foundMarker[1]);
                            Console.WriteLine("Destiation " + foundMarker[1] + " ID: " + destinationId);
                            qp.AddLinkToDestination(x, y, width, height, destinationId, 1);
                        }

and the output is

OutlineId: 1476395014

Created NamedDestination MyPlaceholder

Destiation MyPlaceholder ID: 0

Is this even the way to do it or can i skip named and get straight to an LinkID?

Cheers

Simon

I have tried a different approach since i can get the page number of the outline and they are always at the beginning of a page but NewDestination is still 0

int outlinePage = qp.GetOutlinePage(outlineId);
Console.WriteLine("OutlineId: " + outlineId + " on page " + outlinePage);
int destinationId = qp.NewDestination(outlinePage, 0, 7, 0, 200, 0, 0);
Console.WriteLine("Destination " + foundMarker[1] + " ID: " + destinationId);
qp.AddLinkToDestination(x, y, width, height, destinationId, 1);

Output:

OutlineId: 1476395022 on page 14

Destiation MyPlaceholder ID: 0

So i think there is something in general i don't understand

Cheers

Update

Turns out i can skip the destination which i can't get to work anyway, I'm using

qp.AddLinkToPage(x, y, width, height, outlinePage, 0, 0));

now which is finally working.

Would be interesting tho what went wrong with my destinations, i might need them in the future...
